Comment (by asn):

 Please find an initial version of (a) in my branch `bug20852`:
 https://gitweb.torproject.org/user/asn/tor.git/log/?h=bug20852

 It basically does two things:
 - Changes `encrypted` to `superencrypted` in the outter HS desc layer.
 - Changes the max descriptor size to 50kb and introduces a consensus param
 `HSV3MaxDescriptorSize` that controls it.

 I believe these two things address everything that was pending in prop224
 and has to do with HSDir parsing of HS descriptors. Please check out the
 branch. I'm gonna do another pass of prop224 to make sure I didn't miss
 something.
